Features
- Advanced design with simple mechanism, strong stainless steel float to prevent cracking during sudden water hammer & quick closure.
- Aerokinetic mechanism to resist blow shut under higher air velocity even up to sonic velocity of air.
- 100% Spill Free: Enlarged body specially designed to lower the sewage water flow speed, short stroke designed for quick closure and internals shape engineered to prevent splash even with turbulent flows.
- Keeps dirty or corrosive liquid inside the body for safety during operation and prevents harming operators & surrounding environment.
- Internal body guide and upper round wall restrict float movement on its rail and keep liquid turbulence within this area.
- Much larger air flow through the nozzle even for higher viscosity liquid.
- All iron parts are coated inside & outside with fusion bonded epoxy for corrosion resistance as per AWWA C550.
- Sewage Air Release Valve fully complies with manufacturing standard AWWA C512 and BS EN 1074-4.
